Heated discussions about the wondrous math problem on the Internet!

At the same moment.

A math problem had suddenly caused a stir on the seemingly calm Weibo!

A Weibo verified user whose account belonged to a Beijing No. 2 Experimental Primary School teacher had posted an elementary math problem online: "Who can answer this? Everyone, come and give a try!"

At the beginning, no one really thought anything about this. On seeing the call for a challenge to solve the question, at most some people would come and take a look at it, thinking that an elementary math problem couldn't possibly be too difficult. Even secondary level math questions were not a problem for them, besides, who hadn't studied in primary school before? And so, someone began with an attempt to answer the question but just as they seriously started reading the question, they found that it was basically different from what they had expected!

"Damn! What the heck! F**k!"

"What kind of math question is this?"

"There's music?"

"Is this an elementary math question?"
